Can someone please tell me what this is? Little background. 29 year-old female with ulcerative colitis (in remission). Just gave birth in August. Feeling healthy, no symptoms, other than this is my stool. Had it tested at a lab and came back as nonparasitic. Could they be wrong? I should also mention that I take Canasa suppositories, but I don't remember ever seeing this kind of stuff. It is continuing. I should also mention that when we thought it was worms before we got the lab results back, they put me on 3 days of Vermox, so in theory, if it was worms, it would have been taken care of....Help! What is this?!?
